   版式约定（SEO-20260926）
   ------------------------------------------------------------
   本站现行卡片体系是 .article-grid / .side-card / .overview-grid。
   下面这些类当前没有任何页面在用，但它们是「通用版式」而不是死代码，
   保留是有意的：对标国内景点官网后确认待补的四块内容会直接用上——
     .gear-tags  → 行前准备清单（装备标签）
     .notice / .notice-grid / .notice-item → 通用规则与禁止事项
     .transit-list / .time-block → 通讯、充电、补给点分布
     .price-table → 门票退改与二次入园规则
     .around-card / .stay-card   → 周边玩乐与沟口住宿卡片
   删之前先想清楚这块内容是不是已经做了。
   另有一类真正的死代码已清理：四季切换组件（.season-* / .v-*），
   那是 2026-09 下线功能留下的，js/main.js 里的对应逻辑同时已删。
